In this commentary, we analyze the adaptive functions of shared narratives in tandem with affective structures, in order to better complete Conviction Narrative Theory. The conveyance of stories, in environments of extreme doubt, is inescapably colored by emotions and firmly grounded in collective recollections. For humans experiencing adversity, narratives possess important evolutionary functions, acting as the social mortar binding individuals together.
To further strengthen Conviction Narrative Theory, I recommend Johnson et al. integrate it more deeply with prior work in decision-making, specifically the pioneering research of Herbert Simon. Beyond that, I am wondering about the ways in which further contemplation of narratives could help to resolve two interrelated grand difficulties in the field of decision science: accurately describing decision-making contexts; and comprehending the strategies by which individuals choose among decision-making options in those contexts.
The multifaceted nature of Conviction Narrative Theory (CNT) presents significant challenges for critical evaluation. YC1 The plan of action, disappointingly, lacks the critical component of active engagement with the world. For a rigorous research program to test the account, a careful investigation into the developmental and mechanistic procedures of CNT is crucial. A unifying account, driven by the active inference framework, is what I suggest.
Recognizing the dynamic relationship between imagination and social context in the creation of conviction narratives, we hypothesize that the form of this interaction determines the degree of epistemic openness and adaptability in updating narratives, ultimately leading to an enhanced potential for effective decision-making.
Narratives, characterized by a systematic relational structure, are exceptionally well-suited for the transmission of information across cultures. Narrative's relational architecture partially imparts a sense of causality, however, this structure also intricately links narrative elements and different narratives, thereby creating difficulties for both the transmission and the selection of cultural components. The observed correlations hold significant implications for how systems adapt, become complex, and maintain resilience.
Conviction Narrative Theory asserts that reasoners select a narrative that appears fitting to explain the existing data, proceeding to envision potential future outcomes using this chosen narrative (target article, Abstract). Building upon feelings-as-information theory, this commentary analyzes the interplay between metacognitive experiences of ease or difficulty and narrative processing, confirming that fluently absorbed narratives are more likely to be perceived as true.
Recent policy pronouncements and scholarly articles advocate for transforming artificial intelligence into a form of intelligence augmentation, envisioning systems designed to focus on and amplify human capabilities. Based on firsthand observation at an AI company, this article investigates how predictive systems are developed and deployed by developers in collaboration with stakeholders from public sector accounting and healthcare. Based on STS theories of values in design, our examination of empirical data concentrates on how objectives, formalized actions, and work distributions are integrated into both systems and who is disproportionately affected. Our findings suggest that the development of the two AI systems reflects managerial interests in cost-efficiency, driven by political motivations. The outcome is AI systems that are created as managerial instruments to achieve gains in efficiency and reductions in costs, subsequently applied to professionals on the 'shop floor' in a hierarchical method. From our investigation and a review of foundational texts in human-centered systems design of the 1960s, we posit that the transition of AI to IA is dubious, and ask what practical form human-centered AI might take and if it represents a genuinely achievable ideal. Given the ascendancy of big data and AI, a reconsideration of the relationship between humans and machines is imperative to engendering a more authentic and reliable discourse on responsible AI.
There is a pervasive sense of uncertainty surrounding human lives. Wise individuals exhibit the skill of interpreting these ambiguities. Sense-making depends on narratives, and narratives are at the forefront of human everyday decision-making. Perhaps radical uncertainty is itself a constructed and elaborate narrative. Additionally, do common people typically perceive such accounts as lacking in sound reasoning? These questions are put forth to strengthen the theoretical framework of choice under conditions of uncertainty.
Chronic, low-grade inflammation, a hallmark of aging, pervades multiple tissues, a phenomenon known as inflammaging, and significantly raises the risk of numerous age-related chronic illnesses. Yet, the underlying mechanisms and regulatory networks for inflammaging across different tissue types have not been completely elucidated. Using young and aged mice as models, we characterized the transcriptomes and epigenomes of the kidney and liver tissues, finding a shared inflammatory activation signature in both tissues. We further demonstrated, through integrative analysis, a correlation between changes in the transcriptome and chromatin dynamics, identifying AP-1 and ETS family transcription factors as possible controllers of the inflammaging response. Subsequent on-site confirmation revealed that c-JUN, a component of the AP-1 family, primarily activated in aged renal and hepatic cells, whereas elevated SPI1, a member of the ETS family, was largely prompted by increased macrophage infiltration. This suggests distinct mechanisms for these transcription factors in inflammaging. Functional data indicated that the genetic suppression of Fos, a substantial element of the AP-1 family, resulted in a significant decrease of the inflammatory response within the aging kidneys and livers. Through comprehensive analysis of kidney and liver samples, we identified conserved inflammaging signatures and regulatory transcription factors, offering potential targets for anti-aging therapies.
As a potent treatment for hereditary diseases, gene therapy promises considerable advancements. By utilizing cationic polymers, liposomes, and nanoparticles, gene therapy facilitates the condensation of DNA into polyplexes, utilizing the principles of electronic interactions. At this point, the target cells are supplied with a therapeutic gene, which then causes the restoration or modification of cellular processes. Despite the potential, the efficiency of gene transfer into living tissues is unfortunately hampered by factors such as high protein binding, inadequate targeting mechanisms, and substantial entrapment within endosomal compartments. Gene carriers' surfaces can be modified by introducing artificial sheaths comprised of PEG, anions, or zwitterions to prevent interactions with proteins, but this modification negatively impacts cellular uptake, endosomal escape, targeting precision, thus reducing gene transfection. section Infectoriae The reported results demonstrate that attaching dipicolylamine-zinc (DPA-Zn) ions to polyplex nanoparticles produces a significant hydration layer, which mimics the protein-repellent action of PEGylation. This strategy leads to increased cancer cell targeting, enhanced cellular uptake, and facilitated endosomal escape. High gene transfection is possible with polyplexes, provided they have a prominent hydration layer on the surface, even in a 50% serum environment. biologically active building block Cellular uptake and endosomal escape are significantly improved by this strategy, which also effectively addresses the problem of protein adsorption.
Total en bloc spondylectomy, a critical surgical procedure for spinal tumors, permits complete removal of the diseased vertebral body using a specialized T-saw. Nevertheless, the established TES procedure and the presently employed surgical instruments present certain drawbacks, potentially extending operative duration and increasing the likelihood of complications. In order to circumvent these hindrances, we designed a modified TES technique employing a home-built intervertebral hook blade. Our study sought to describe our modified total en bloc spondylectomy (TES) technique, utilizing a custom-made intervertebral hook blade, and evaluate its clinical effects in individuals diagnosed with spinal tumors.
A series of twenty-three patients with spinal tumors, seen consecutively between September 2018 and November 2021, were part of this investigation. Eleven patients had a modified transforaminal endoscopic surgery (TES) performed with an intervertebral hook blade, whereas twelve patients underwent a conventional TES using a wire saw. The modified TES technique's specifics were presented, along with a review and analysis of intraoperative blood loss, operative duration, and improvements in pain symptoms and neurological function, as assessed by the visual analog scale (VAS) and American Spinal Injury Association (ASIA) scores for each patient. To evaluate differences in clinical outcomes, a nonparametric analysis of covariates (ANCOVA) was applied to patients receiving modified TES and conventional TES.
The modified TES protocol significantly decreased operative duration (F=7935, p=0.0010), resulting in positive changes in neurological function (F=0.570, p=0.0459) and pain reduction (F=3196, p=0.0088) as opposed to the conventional TES group. The conventional TES group (355833 ml) had a higher mean intraoperative blood loss than the modified TES group (238182 ml), although this difference was not statistically significant (F=0.677, p=0.420).
A modified TES technique incorporating an intervertebral hook blade can effectively minimize operative time and intraoperative hemorrhage, while simultaneously improving neurological function and reducing pain, highlighting its promising application in spinal tumor management as a safe and effective procedure.
A modified TES technique incorporating the intervertebral hook blade leads to a reduction in surgical time and intraoperative hemorrhage, while positively impacting neurological function and pain relief. This modified approach is thus demonstrably feasible, safe, and effective for addressing spinal tumors.
